Hi Guys i hope somebody who knows about capacitive touch screens can help me! I have taken my HD2 apart to fix a smashed camera lense. On removing the back cover i used a small screwdriver to prise off the back case and unclip it all round. It came off with no problem, i fixed the camera and put it back together. When i turned the device back on the touch screen isn't responding to my finger on any screen. Like i turned the touch screen off! The hard buttons still wok but nothing from the screen. Nothing looks damaged (I.e the glass isn't smashed). I seem to think i might have damaged something when prising the cover off with the screwdriver. Please, any suggestions would be really helpful!!!
Can anybody out there help with this? I am currently without a phone :-(
I have exactly the same problem, but it happened from nowhere. I didnot unscrew anything. Please Help
Check the flex cable.. this part are very delicate.

same problem
ive got the same problem, mine just stopped working, i performed a soft and hard reset, removed the battery still nothing. it worked for a moment but once locked it stopped working again, only the hard buttons.
same problem but it works on and off. basically the screen will respond until the phone is put into hibernate. the after that id have to push the phone button and end button back and forth until it responds
Same Issue independant of ROM
Same issue here.
Funny thing is it started a week or two ago randomly out of the blue.
Same scenario:
lock the phone can't get touchscreen to respond for unlock
Judging by these posts everyone started seeing this about the same time, maybe it's a software issue or background app .
Help!
I have same problem. It can work for a couple of hours or in 1-2 days then just stop responding, almost every time when in hibernate. Lets just hope it's not hardware failure.
This started happening to me this morning. Out of 50 tries, managed to unlock the phone three times only. This happened out of the blue, right after i removed my phone from the charger.
Have soft reset, hard reset, reflashed ROM, but the issue still remains.
I really really hope this is not a hardware issue.
Does anyone out there know how to solve this? My phone is virtually unusable right now...
Same problem here, I've been testing for about 2,5 months now and today I've sent mine back to HTC . I think it's a hardware problem, tried everything from hard resetting to reflashing. When I press the HTC logo and keep it pressed the screen does respond again. Conclusion: hardware problem.

You're probably right.
I've also tried everything. But kind of strange that if I lock when not on home tab it seems to work. And the screen, almost always, reacts as it should as long as I just dont' lock it.
I just started to get this issue. touch screen works fine until it hibernates. reflashed, still happens. found this in my search:
htcphones.net/htc-hd2-problems-with-touchscreen/
just got off the phone with tmo. they are sending me a new one.
Yeah, it happened to me as well. I opened a new thread like a month ago explaining the problem: http://forum.xda-developers.com/showthread.php?t=710282&styleid=15
and I contributed in another one concerning the same issue here: http://forum.xda-developers.com/showthread.php?t=708530
Summing all up, it ain't caused by a software or a ROM of some kind (at least in my case) because soft and hard resets didn't solve it nor did the flash of a stock ROM. The most probable cause is a digitizer (touchscreen) defect that appears randomly and totally out of the blue. The only thing to do in my opinion is to send the phone in for repair, which I did. It came back with a check mark on "calibrated screen" checkbox. As of now phone's working fine and I hope they solved it even though I read of other people who have had their leo's screens completely replaced..
A curious side note: htc care reset to zero my phone's call duration timers..
I'm not sure if it's the screen. In my case I think it's the connector from the screen to the motherboard, because pressing the housing seems to help.
But let's see if HTC is able to repair it, I hope they are, because the problem is so random they might not even see it
After losing functionality on my touch screen for a week, finally decided to send it in. Took the trouble to revert my HSPL to original and Stock Rom.
Repair should take about a week. Now I'm stuck with an ancient Nokia 6230i for this week. I feel so lost without my ppc. Have had one for as long as I can remember.
Hopefully the phone comes back okay...
I've had so much problem with the screen not responding so I did all backup then reflashed, hard reset to put the device back to stock. Did this during the weekend, I even fired up my old iphone 3g to have as backup phone.
All set today to go to the store and have it repared under warranty.
But since Sunday evening it works perfect. I've been testing it a lot and the screen has not stop responding even once.
This might be just temporarily but does anyone else experienced something like this?
Mine sometimes worked well for hours... days... but eventually the problem came back.
Mine died on me when I was actually out of the country (stuck in Vietnam without a phone). It would work for 5 minutes, then stop for hours. I would have to switch my phone on and off for a couple hundred times before it worked for another 5 minutes...
Got so tired of it that i sent back my HD2 for warranty repair. Expect it to be back tomorrow (or Friday at the latest). Hope there's no further problems with it.
I hate to say it, but the HD2 is known for its highly defective touchscreen. Even when it's working, a lot of people experience strange and bothering events, such as the touchscreen "touching" itself, a very high/very low screen sensitivity all of a sudden, the tilting of the screen to one of the four corners of the device and so on and so forth.
With a device so expensive one would expect it to work flawlessly. Seems to me that HTC doesn't think the way we do...
So for some reason, the last few days the touchscreen on my phone was being super slow, and id have to turn off the screen, then turn it back on multiple times and keep trying to slide it to unlock. I dont know how this started. Ive been using the NexusHD2-Gingerbread V2.9.
Ive tried other ROMs and restored previous backups and nothing is working. The screen is still not responsive. Ive never had this happen before and not sure what else to do. Its just stuck on the lock screen but everything is unresponsive....any ideas???

Unfortunately, your touchscreen digitizer is dying. This is related to the hardkey malfunction. The only thing you can so now is flash back to stock WM Tom and send it back for repair. The phone's touchscreen need to be replaced.
Good luck,

Yeah thats what ive been reading, and right after i started this thread i was reading on another and read that you can fix it if you hold the power button down firmly (apparently the digitzier is right behind it)....that worked for me.
I think too much flashing and changing ROMS using the power button didnt help hehehe

Try using zMooth or Button Savior. This help your hardkey a lot. Since I have zMooth and Button Savior install on my phone, I no longer have to use the hardkey.

for how long (holding of power button) ????
{edit}
!!!!! FIND SOLUTION !!!!!
The digitiZer is under the hangup button. press the button bit hard till it nudges the digitiser a little. it worked for me.
(found it from : http://www.htcphones.net/htc-hd2-problems-with-touchscreen/ )
I'm so cool now!!
I have been living on this solution for almost 2 months now.
However I can't take it anymore not because I am lazy!
but because when sometimes you need to make a quick call or grab that
camera instantly I tend to waste a good 5 minutes trying to make that hardpress on the end key work with the digitizer cable.
My question is, would changing the digitizer work? or is it something else?
Ever noticed that T-Mobile HD2 has soldered digitizer connection to the LCD vs. flex-cable socket in standard Leo?
I was running an older Paramid version of dunphp's ROM, and right before swtching the ROM my touch screen start to not function. I could not pull the ring up to unlock the screen. I rebooted multiple times. Cleared Dalvik and fixed permissions. It finally worked after attemptiing to unlock it for what seem like abother 500 times.
I was going to change over to his latest Deisre HD ROM anyway. So I did a Task 29, and cleaned and reinstalled everything from scratch. It worked perfectly for about 5 days. Now I am getting the same issue with my touch screen. It just seems to go out. Is this typically what happens when it's about to die?
Never mind. I Task29, and flashed a Windows Mobile ROM just to see, and yeah...it's dead...

You have semi-dead digitizer. But it is nothing you can't temporarily fix every time it happens. Just push red (end call) button really hard for a while and it will get fixed for a while. I recommend you using button savior and lock screen with it and unlock with any other button than red one, it should be permanently fixed then. Please hit the thanks button if I helped you.

I hit the thanks button as you gave me hope. I am currently using my old TouchPro 2 with an old NRG Titanium Rom on it for the time being, but will try this today. I’ll install “button savior”, but what am I supposed to do with the app? What settings do I run? I think you are totally right about this, as I noticed when I was unlocking my phone, using the green call button worked most often, but now that’s not even working.

Yes, I have exactly the same problem as you have. My phone was working flawlessly for like a year and a half, but last week all of a sudden the touchscreen sometimes didn't work and sometimes it did. So I tried literally everything, I was fixing my permisions all the time, wiping dalvik, task29, remaking parrtitions, even bought a new sd card. But few days ago I found a solution, by pushing red button really hard (because the digitizer is right behind it) and not using it after. The Button Savior app is a simple app that makes a very little transparent icon on your screen and when you tap it, the menu of buttons will come up (with the same buttons as your hard buttons on your device) so every time you will want to lock the device you will do it on your screen, and won't have to push the hard button and come through all the hassle of pushing the digitizer. I really hope I helped you, as this very same problem was driving my crazy for the past few days.

Aww, that's a shame. I really tought it would help. It doesn't work every time, maybe you can try it few more times. If it's not even then going to work, then maybe you should get your digitizer replaced.

How long do you hold the red button? Also, I am pushing down really hard. I didn't know you could get the digitizer replaced...I wonder who would do that (no way would I send it to HTC and wait a month), and how much that costs...?
HTC sends phones back crazy quick. Atleast that's how it was for me. They actually sent it back the day they got it from what I remember. It did take a while though for the phone to arrive to HTC (this depend who and from where you send it though) If your phone still has warranty I seriously recommended you send it yo HTC. Just remember to flash it 100% stock before sending it.

Well believe it or not, after pressing the Red phone off button for an eternity and applying a ton of pressure, it's working. I am sure it won't be for long. I have a shortcut to lock the phone on the screen. So basically your saying I should stay away from hitting the Red phone off button, or else that will kill it again? What about the other hard buttons?
I am in the UAE at present, so it might be better for me to just order a digitizer and do the repair myself. I see there are a lot of YouTube videos on the subject.
Thanks everyone for your help!
First of all, I have been using this phone for over 18 months without any issues it is an amazing phone, but, all of the sudden all lower buttons (back, home and search) are not working anymore. It all started a few days ago and only the Home button started to fail but worked again after a phone restart, and now even after a restart all 3 buttons does not work
So far I have tried:
1. A hard reset, lost all my data but that did not fixed the buttons.
2. Opened the phone uncovering the display and mainboard trying to see if a cable was not fully plugged in but no, then I assembled it again. This made the buttons works for almost a day but then failed again.
My phone is already out of warranty, does somebody has/had the same issues?, what can I do to resolve or should I just get a new phone???

Just let the phone rest for a day, or 3 days, then check it but dont turn it on until the days passes. Usuall this works for all phones with touch panel.

My back, search, camera, home, & up volume is not working at all. I have to turn off and on my phone if I want to go to a different app. I have took the battery out, tried turning it off, and 100% rebooting it (and loosing everything) but nothing seems to be working.
Not sure what to do now. I really need my phone and cant afford to get a new phone. It sucks having to turn it off and on so much and it is killing the battery.... :crying:

Hello, suddenly my softkeys stopped working, I already tried doing a factory reset, reflash a different rom, but still no go.
What's strange is that even on landscape mode the keys dont work.
It doesn't seem to be a problem with the touch screen since the touch screen works fine as long as the soft keys aren't present.
Any help? Thnx!

Hi Salvy,
Did you flash a mod or another kernel?
It's a very common problem with the Nexus 4. I've been using paranoid android pie for 6 months to work around the issue. I can confirm that it is a hardware issue and not a software problem. A quick Google search can tell you that.
Sent from my Nexus 4 using xda app-developers app
Got the same damn problem. I would normally use a smart phone for at least 18 months but the Nexus 4 only lasted 14 months. I was hoping to use it till the Nexus 6 came out but after sending it off to be fixed, using a dumb phone for 10 days and the phone came back with the same problem, I had to go buy a Nexus 5
My soft keys work in portrait but not in landscape. I enabled the 'show touches' option in developer mode and I can see the lower 4mm of the screen isn't registering any touch. Do a quick search on Google and you'll find there are loads of people out there with the same problem. The only solution is to change the screen and I haven't seen anyone manage to get it changed under warranty . I have sent it back and expect them to fleece me off £100 for a new screen.
Disappointed with the quality of the N4 but I had no choice but to get the N5 even though it is also by LG cause once you go Vanilla, you cant go back

Ok. so I have been told by the LG service centre in Mumbai that this happens when an android update doesnt get installed properly, it definately is an android update problem according to the service centre. But since i am out of warranty by @ DAYS I have to pay Rs. 5300 for no fault of mine... ****ed up!!!
I found a solution somehwere on the internet!!
I had this problem for the last day this is the solution.
Download the application: GMD Auto Hide Soft Keys ★ root
Use it, toy with it and restart your phone. And it just works.
This worked with unrooted phones aswell, as the solution said. I don't know.
Your welcome!

I paid Rs 4700 which includes service charge, taxes etc in addition to the cost of the screen+ digitiser. The guys at service center dont have separate screen and digitiser but just both of them as single replacement. I just hoped that they could have better service centers and support, but you cant help.
Using `wm` command on phone via ADB shell to add an blank border on screen

I used virtual buttons for awhile, but in the end, discovered a way to do it without rooting, so long as you have the `adb` command line tool installed for development, and don't restart your phone that often:
From a command-line termal:
```
# Log into a device connected via USB.
# (Look for a tutorial on using adb, as it need some config on the phone)
adb shell
# Change the screen "overscan" using the window manager tool on the phone:
wm overscan 0,0,0,80
```
The trick is that, overscan essentially adds a buffer (black bar) on any side of the screen for positive numbers. (the screen extends "offscreen" for negative ones.) `wm --help` will show you that the accepted format of overscan is:
```
wm overscan [reset | LEFT,TOP,RIGHT,BOTTOM]
```
ie. you can either reset it to default, or set any border. In my case, I set the bottom border to 80 pixels, and that was enough to avoid the non-responsive section of the touch screen.
Of course, I assume this reset on reboot, but haven't tried yet. If it does, I'm sure someone can figure out a clever way to make it persist
Anyhow, hopefully this helps!

It worked for me. I had the same Problem and it occur when i bought new power cable. The i plugged the original blackberry micro usb cable for power up and it started working for me. Its weird but the cause of the problem is when i plugged the cheap micro USB.

Issue:
-Softkeys not working when located on the side of the screen closest to the charging port. Softkeys would work when the screen was rotated such that the softkeys were located on the side of the screen closest to the headphone jack.
Device:
-Nexus 4 running 5.1.1
Conditions:
-Battery was 85%-90% charged
What fixed the issue:
-Plugged the phone into a USB charger. I did not use a Nexus charger; I used a random LG charger I had laying around.
-Pressed and held the power button for 30 seconds. The phone powered off after ~10 seconds. Shortly after the phone powered off, the notification light flashed red for the remainder of the 30 seconds.
-Powered the phone back on. When the phone was finished booting up, the softkeys worked again.
What didn't work:
-Restarting the phone multiple times
-Restarting into Safe Mode
-Disabling Chrome (Settings >> Apps >> Chrome >> Disable)
